Description

Technical Field

[0001] This utility model relates to the field of laser cladding equipment technology, and in particular to a laser cladding head. Background Technology

[0002] Laser cladding is an advanced surface modification technology that uses the synergistic effect of a high-energy laser beam and metal alloy powder to form a metal coating with specific properties on the surface of a substrate. This technology not only significantly improves the wear resistance and corrosion resistance of workpieces, but also effectively extends the service life of tools.

[0003] Most existing laser cladding devices have a fixed laser head angle, and the position of the laser head can only be adjusted by raising and lowering. When dealing with complex workpieces that require cladding at multiple angles, it is often necessary to frequently adjust the workpiece posture, resulting in cumbersome operation procedures and low work efficiency. Moreover, the fixed laser head angle may also cause the relative position of the laser beam and the workpiece surface to be less than ideal, which in turn affects the quality of the cladding layer and causes problems such as uneven cladding and insufficient bonding strength. Utility Model Content

[0004] The purpose of this utility model is to provide a solution to the problem that most laser heads are fixed at a fixed angle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser cladding head includes a frame and a laser head body, wherein the frame is equipped with an adjustment mechanism capable of adjusting the cladding angle of the laser head body;

[0007] The adjustment mechanism includes an electric telescopic rod fixedly installed on the frame, and a lifting frame is fixedly installed at the output end of the electric telescopic rod. The lifting frame is equipped with a rotating component that can rotate the laser head body to different angles.

[0008] It also includes a conveying mechanism mounted on the frame, the conveying mechanism including a movable groove opened on the frame, a lead screw rotatably connected inside the movable groove, a turntable fixedly connected to one end of the lead screw, and a fixing component capable of clamping the workpiece mounted on the lead screw.

[0009] As a further description of the above technical solution:

[0010] The rotating assembly includes a first motor and a second motor fixedly mounted on the lifting frame. A first arc-shaped frame and a second arc-shaped frame are rotatably connected to the lifting frame. The interiors of the first arc-shaped frame and the second arc-shaped frame are connected and have grooves. A first slider is fixedly connected to the bottom end of the lifting frame. A spherical component is slidably connected to one side of the first slider. A second slider is slidably connected to one side of the spherical component. An extension frame is fixedly connected to one side of the second slider and located between the grooves.

[0011] As a further description of the above technical solution:

[0012] One end of the first arc-shaped frame is fixedly installed on the output end of the first motor, and one end of the second arc-shaped frame is fixedly installed on the second motor. The first arc-shaped frame and the second arc-shaped frame are staggered.

[0013] As a further description of the above technical solution:

[0014] The second slider moves with the second arc frame, the first slider moves with the first arc frame, and the laser head body is fixedly mounted on the extension frame by screws.

[0015] As a further description of the above technical solution:

[0016] The fixing assembly includes a bearing plate threaded onto the lead screw, a groove is provided at the top of the bearing plate, a positive and negative threaded lead screw is rotatably connected inside the groove, clamps are threaded to both sides of the positive and negative threaded lead screw, one end of the positive and negative threaded lead screw extends to the outside of the bearing plate and is fixedly connected to a worm gear, and a worm is rotatably connected to one side of the bearing plate.

[0017] As a further description of the above technical solution:

[0018] The worm is mounted on the side near the worm wheel and meshes with the worm wheel. The height of the worm is greater than that of the clamping plate.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. By incorporating an adjustment mechanism, when the first arc-shaped frame swings and drives the extension frame to move, the extension frame slides the spherical component on the first slider via the second slider. At this time, the second slider cannot rotate, thereby achieving adjustment of the laser head body's front-to-back position and angle. When the second arc-shaped frame swings and drives the extension frame to move, the extension frame moves left and right on the spherical component via the second slider, while the spherical component is blocked by the first slider and cannot rotate, thereby achieving adjustment of the laser head body's left and right position and angle. By setting the second arc-shaped frame and the first arc-shaped frame, the movement path of the laser head body is consistent with the curvature of both. In this way, the laser head body can flexibly rotate to any desired angle and position within the arc range defined by the second arc-shaped frame and the first arc-shaped frame to meet the cladding requirements under different working conditions.

[0021] 2. By setting up a conveying mechanism, the workpiece is placed on the carrier plate, and the workpiece is clamped and fixed by the rotating positive and negative threaded screw. Then, by rotating the screw, the carrier plate moves the workpiece to below the laser head body, ensuring the stability of the workpiece during the cladding process and preventing uneven or misaligned cladding layers caused by workpiece movement or vibration. This can greatly improve the accuracy of cladding and achieve a better bonding effect between the cladding layer and the substrate. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figure 1 - Figure 6 As shown, the present invention provides a laser cladding head, including a frame 10 and a laser head body 20. The laser head body 20 is a prior art technology. Its principle is as follows: the optical pump source (such as a flash lamp or laser diode) inside the laser head body 20 provides high-energy light energy to the working material (such as Nd:YAG crystal). When the laser beam reaches a certain energy intensity in the optical resonant cavity, some reflectors will allow a portion of the laser beam to pass through, thereby outputting high-energy laser, which heats and melts the repair powder on the workpiece. The frame 10 is equipped with an adjustment mechanism 30 that can adjust the cladding angle of the laser head body 20.

[0035] The adjustment mechanism 30 includes an electric telescopic rod 31 fixedly installed on the frame 10. A lifting frame 32 is fixedly installed at the output end of the electric telescopic rod 31. The lifting frame 32 can be driven to descend by the electric telescopic rod 31. A rotating component 33 is installed on the lifting frame 32, which can rotate the laser head body 20 to different angles.

[0036] It also includes a conveying mechanism 40 mounted on the frame 10. The conveying mechanism 40 includes a moving groove 41 opened on the frame 10. A lead screw 42 is rotatably connected inside the moving groove 41. One end of the lead screw 42 is fixedly connected to a turntable 43. The lead screw 42 can be rotated by rotating the turntable 43. A fixing component 44 capable of clamping the workpiece is mounted on the lead screw 42.

[0037] like Figure 2 - Figure 5As shown, the rotating assembly 33 includes a first motor 331 and a second motor 332 fixedly mounted on the lifting frame 32. A first arc frame 333 and a second arc frame 334 are rotatably connected to the lifting frame 32. The first arc frame 333 and the second arc frame 334 have the same curvature. The interiors of the first arc frame 333 and the second arc frame 334 are connected and have grooves 335. A first slider 336 is fixedly connected to the bottom end of the lifting frame 32. A spherical component 337 is slidably connected to one side of the first slider 336. A second slider 338 is slidably connected to one side of the spherical component 337. An extension frame 339 is fixedly connected to one side of the second slider 338 and located between the grooves 335.

[0038] In more detail, one end of the first arc-shaped frame 333 is fixedly installed on the output end of the first motor 331, and one end of the second arc-shaped frame 334 is fixedly installed on the second motor 332. The first arc-shaped frame 333 and the second arc-shaped frame 334 are staggered. When it is necessary to adjust the angle of the laser head body 20, the first motor 331 is started, which drives the first arc-shaped frame 333 to start swinging. Since the extension frame 339 is located in the groove 335, the extension frame 339 will be driven by the groove 335 while the first arc-shaped frame 333 is swinging. The extension frame 339 will cause the spherical part 337 to rotate through the second slider 338, so that the spherical part 337 slides on the first slider 336, thereby adjusting the position and angle of the laser head body 20.

[0039] When it is necessary to adjust the position of the laser head body 20 left and right, the second motor 332 is started, and the second arc frame 334 is driven to swing by the second motor 332. At this time, the extension frame 339 is driven by the groove 335. The extension frame 339 will then move left and right on the spherical part 337 by the second slider 338. At this time, the spherical part 337 is blocked by the first slider 336 and cannot rotate, thereby enabling the laser head body 20 to be adjusted in position and angle left and right.

[0040] Meanwhile, by setting the second arc frame 334 and the first arc frame 333, the movement path of the laser head body 20 is consistent with the arc of the two. In this way, the laser head body 20 can flexibly rotate to any required angle and position within the arc range defined by the second arc frame 334 and the first arc frame 333 to meet the cladding requirements under different working conditions.

[0041] like Figure 5As shown, the second slider 338 moves with the second arc frame 334. When the second arc frame 334 swings and drives the extension frame 339 to move, the extension frame 339 moves left and right on the spherical part 337 through the second slider 338. The spherical part 337 is blocked by the first slider 336 and cannot rotate, thereby realizing the adjustment of the left and right position and angle of the laser head body 20.

[0042] The first slider 336 moves with the first arc frame 333. When the first arc frame 333 swings and drives the extension frame 339 to move, the extension frame 339 causes the spherical part 337 to slide on the first slider 336 through the second slider 338. At this time, the second slider 338 cannot rotate, thereby realizing the adjustment of the front and rear position and angle of the laser head body 20. The laser head body 20 is fixedly installed on the extension frame 339 by screws, and the extension frame 339 drives the laser head body 20 to move.

[0043] like Figure 6 As shown, the fixing assembly 44 includes a bearing plate 441 threaded onto the lead screw 42. A groove 442 is provided at the top of the bearing plate 441. A positive and negative threaded rod 443 is rotatably connected inside the groove 442. The positive and negative threaded rod 443 is existing technology. The threads on both sides of the positive and negative threaded rod 443 are arranged in opposite directions. Clamping plates 444 are threaded to both sides of the positive and negative threaded rod 443. When the positive and negative threaded rod 443 rotates in both directions, the clamping plates 444 on both sides can move towards the opposite or opposite sides. One end of the positive and negative threaded rod 443 extends to the outside of the bearing plate 441 and is fixedly connected to a worm gear 445. A worm gear 446 is rotatably connected to one side of the bearing plate 441.

[0044] In more detail, the worm 446 is installed on the side near the worm wheel 445 and meshes with the worm wheel 445. The height of the worm 446 is greater than that of the clamping plate 444. The workpiece is placed on the bearing plate 441. By rotating the worm 446, the meshing worm wheel 445 begins to rotate. The worm wheel 445 causes the forward and reverse threaded rods 443 to rotate in opposite directions, thereby causing the clamping plates 444 on both sides to move towards opposite or opposite directions to clamp or release the workpiece.

[0045] Working principle: In use, the workpiece is placed on the support plate 441. The worm gear 446 is rotated to make the meshing worm wheel 445 start to rotate. The worm wheel 445 makes the positive and negative thread screw 443 rotate, thereby making the clamping plates 444 on both sides move towards the opposite face to clamp the workpiece. Then, the turntable 43 is rotated to make the thread screw 42 rotate and make the support plate 441 start to move, thereby moving the workpiece to below the laser head body 20. Then, the electric telescopic rod 31 is activated to drive the lifting frame 32 to descend, so that the laser head body 20 descends to perform cladding on the workpiece.

[0046] When the position or angle of the laser head body 20 needs to be adjusted, the first motor 331 is started, which drives the first arc frame 333 to start swinging. Since the extension frame 339 is located in the groove 335, the first arc frame 333 swings while the extension frame 339 is driven by the groove 335. The extension frame 339 then causes the spherical part 337 to rotate through the second slider 338, which causes the spherical part 337 to slide on the first slider 336, thereby enabling the laser head body 20 to be adjusted in position and angle.

[0047] When it is necessary to adjust the position of the laser head body 20 left and right, the second motor 332 is started, and the second arc frame 334 is driven to swing by the second motor 332. At this time, the extension frame 339 is driven by the groove 335. The extension frame 339 will then move left and right on the spherical part 337 by the second slider 338. At this time, the spherical part 337 is blocked by the first slider 336 and cannot rotate, thereby enabling the laser head body 20 to be adjusted in position and angle left and right.

[0048] Meanwhile, by setting the second arc frame 334 and the first arc frame 333, the movement path of the laser head body 20 is consistent with the arc of the two. In this way, the laser head body 20 can flexibly rotate to any required angle and position within the arc range defined by the second arc frame 334 and the first arc frame 333 to meet the cladding requirements under different working conditions.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
